| Description | Pro-neuregulin-1; membrane-bound isoform (Pro-NRG1) [Cleaved into- Neuregulin-1 (Acetylcholine receptor-inducing activity) (ARIA) (Breast cancer cell differentiation factor p45) (Glial growth factor) (Heregulin) (HRG) (Neu differentiation factor) (Sensory and motor neuron-derived factor)] |

| Subcellular Location | [Pro-neuregulin-1; membrane-bound isoform]- Cell membrane; Single-pass type I membrane protein. Note |
| Developmental Stage | Detectable at early embryonic ages. Isoform 10 is highly expressed in developing spinal motor neurons and in developing cranial nerve nuclei. Expression is maintained only in both adult motor neurons |
| Similarity | NA |
| Tissue Specificity | Type I isoforms are the predominant forms expressed in the endocardium. Isoform alpha is expressed in breast; ovary; testis; prostate; heart; skeletal muscle; lung; placenta liver; kidney; salivary gl |
| Post Translational Modification | Proteolytic cleavage close to the plasma membrane on the external face leads to the release of the soluble growth factor form.; N- and O-glycosylated. Extensive glycosylation precedes the proteolytic |
| Function | Direct ligand for ERBB3 and ERBB4 tyrosine kinase receptors. Concomitantly recruits ERBB1 and ERBB2 coreceptors; resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. The multiple isoforms perform diverse functions such as inducing growth and differentiation of epithelial; glial; neuronal; and skeletal muscle cells; inducing expression of acetylcholine receptor in synaptic vesicles during the formation of the neuromuscular junction; stimulating lobuloalveolar budding and milk production in the mammary gland and inducing differentiation of mammary tumor cells; stimulating Schwann cell proliferation; implication in the development of the myocardium such as trabeculation of the developing heart. Isoform 10 may play a role in motor and sensory neuron development. Binds to ERBB4 |
